Thought I would share my settings for this shot. Shot in manual mode, ISO at 200, used Matrix Metering, f/7.1, Shutter Speed 1.3 seconds, Auto White Balance since I shoot in RAW and can change up temperature in ACR. I also did not use a tripod for this shot, instead I sat the camera on the bridge floor and hoped it didn't move too much, which if there are lots of people on this bridge...it does shake!
Post editing was done in Photoshop CS5 and ACR. In ACR, I didn't change much, just moved the black slider a bit to the right, and the clarity slider to the right also. In Photoshop I used a soft light blending mode at 25% opacity. Merged the two layers together and then sharpened using Totally Rads Sharpen Like a Ninja (free) photoshop action.
